I took deck passage on the Nauruan freighter, the CenPac Rounder, aka the CenPac Feckarounder, from Apia to Suva to Nauru. Then I flew Air Nauru to Henderson Field on Guadacanal. I hadn't thought of those crazy days in years. Fun times.

Henderson Field on Guadalcanal, my god that elicit a plethora of emotions as I had some sailing friends that had been through that hell and were heading back many years later to revisit. Gene you had some fantastic adventures in the South Pacific, how about some stories some time.
